DTC B552: Keep Alive Memory Error
NOTE:
When all diagnosis and repairs are completed, clear codes and verify operation.
NOTE:
For circuit identification, see Fig 1
.
Code B552 indicates that the keep alive or "long term" memory in the BCM has been reset. It is a normal occurrence whenever power is removed from the BCM, such as anytime the battery has been disconnected and reconnected. Code B552 may only be cleared if it is not current. Under normal conditions, the code will become history by the following: Key in "LOCK", wait 5 seconds, Key "ON" Re-enter Diagnostics.
This code should now be history, and can be cleared in the normal manner.
